Invasive plant-soil feedback refers to the process by which alien plants alter the physicochemical and biological properties of the invaded soil, thereby creating a feedback loop that affects their own growth and subsequently changes the structure of native plant communities and ecosystem functions. Based on recent research, the key drivers of invasive plant-soil feedback have been identified, including the biological characteristics of invasive plants (e.g., litter and root exudates), soil properties (physicochemical and microbial characteristics), multi-trophic interactions, and other abiotic factors. Current research emphasizes that soil microorganisms are the most critical regulatory factors in the invasive plant-soil feedback process. The roles of soil-borne specialist pathogens or symbiotic microbes in the new environment may be diminished or neutralized by native microorganisms. Substantial progress has been made in the cutting-edge research of invasive plant-soil feedback across different temporal and spatial scales and environmental gradients. However, the integration of multi-dimensional scales is a key trend and new perspective. Based on the current research status of invasive plant-soil feedback, seven challenges and prospects have been proposed, aiming to provide reference directions for further research.
